The following example uses the GetCertHashString method to get an X.509 certificate hash value, convert it to a string, and display it to the console.


using System;
using System.Security.Cryptography.X509Certificates;


public class X509
{

    public static void Main()
    {

        // The path to the certificate.
        string Certificate =  "Certificate.cer";

        // Load the certificate into an X509Certificate object.
        X509Certificate cert = X509Certificate.CreateFromCertFile(Certificate);

        // Get the value.
        string results = cert.GetCertHashString();
       
        // Display the value to the console.
        Console.WriteLine(results);
  
    }

}

import System.*;
import System.Security.Cryptography.X509Certificates.*;

public class X509
{
    public static void main(String[] args)
    {
        // The path to the certificate.
        String certificate = "Certificate.cer";

        // Load the certificate into an X509Certificate object.
        X509Certificate cert = X509Certificate.CreateFromCertFile(certificate);

        // Get the value.
        String results = cert.GetCertHashString();

        // Display the value to the console.
        Console.WriteLine(results);
    } //main 
} //X509
